DISPENSING ATTACHMENT FOR ETHER-CANS.

Specification of Letters Patent.

Patented July 16, 1918.

' Application filed August 18, 1917. Serial No. 186,998.

To all whom it may concern:

Be it known that I, LOUIS SHEINMAN, a citizen of the United States, and a resident of the city of New York, county of the Bronx, and State of New York, whose postofiice address is N o. 944 Aldus street, Bronx, have invented a new and useful Improvement in Dispensing Attachments for Ether- Cans, of which the following is a specification.

Heretofore ether cans have been emptied for the purpose of anesthesia through rubber or cork stoppers which are attacked and ruined by the ether so that there has been a large'wastage both of stoppers and ether. Furthermore, because of this wastage this ether has not been under perfect control at all times and so'the atient may have suffered. The object 0? my invention is to provide a dispensin attachment which will be durable, tight, e cient and always under control so that the patient never suffers from defects in the apparatus and that there is no waste in material. This and other objects are accomplished by my invention, one embodiment of which is herein more particularly set forth. For a more particular description of my invention, reference is to be had to the accompanying drawings forming a part hereof, in which;

Figure 1 is a side elevation of a can provided with my improvement.

Fig. 2 is a plan view of the same.

Fig. 3 is a sectional view taken on the line 33 of Fig. 2, looking in the direction of the arrows.

Throughout the various views of the drawings, similar reference characters designate similar parts.

The ether can 1 to which my attachment 2 is applied is of the conventional kind with its flaring mouth 3 which is used when the can is either filled or emptied.

The attachment 2 has a frustum of a cone divided into two parts, 4 and 5, which are united at one end by the hinge 6 and at the other by the screw 7 which has one end pivotally mounted on one part 4 and the winged nut 8 on this screw 7 takes over the slotted ear 9 on the other part 4 so that the screw 7 may swing clear of the ear 9 when the attachment 2 is put in position or removed.

This frustum has a flange 10 at the larger end which takes over'a metal disk 11 which is fixed to the part 4 and carries a disk stopper 12 lined with cork or other suitable material which fits with an ether tight joint against the mouth 3 and carries also tubes 13 and 14, the former extending to the bottom of the can 1 and the latter is open to the bottom of the cork disk 12. The tube 14 is open to atmospheric pressure and the tube 13 has both external and internal screw threads so that it may be provided with a spraying cap, as shown at 16, or a dropping device as shown at 17 Or it may be used without either for a large spray stream when such is required. In any event, the outflow is controlled through the kind of nozzle used and the pressure caused by the atmosphere exerted through the opening at the end of tube 14.

In view of the foregoing, the use of my improvement will be readily understood. Assuming that the can 1 is received in the conventional way, itsstopper removed and the attachment 2 placed as shown, and that ether is in the can, air under pressure enters the opening at the end of tube 14 and then liquid ether is forced through the tube 13 and from theapparatus in the form of drops, spray or a stream, according to the attachment employed. The cork disk 12 always insures a tight joint because it is forced against the mouth 3 by the force of the frustum and the pressure exerted through the screw 7 and the tighter the application of the screw, the tighter the joint at the disk 12. Because of this tightness of joint at all times and the other features above mentioned, the ether is always under control and does not injure the patient through any defect in the attachment 2.

While I have shown and described one embodiment of my invention, it is obvious that it is not restricted thereto, but is broad enough to cover all structures that come within the scope of the annexed claim.

v What I claim is: V

In a device of the class described, a cork 5 with openings, one of which has a tube extending to a point near the bottom of an ether can when the flevice is in piece on this can, the other opening being connected. to

an air pressilre tube, a disk on said cork and attached to said tube, a frustum attached to 10 said disk and means for forcing said; frustum against said can to cause the cork to fit with an ether tight joint,
